[Beginner Q] How to use subs/functions from external file?

[NakedApe]

It would be really convenient if main code could be put before, in between and after subs and functions.
I don't see any (compatibility) issues in supporting that in the future ?

Well (of course) main code does go before subs and functions now, but how would the other options be convenient for you? I’d think it would be harder to find things if main code could be put anywhere, bwdik…
